    PKI 2180 Professional Module Stethoscope Recorder

This PKI development outperforms all previous experiences you have made with respect to recorder surveillance so far. A wide variety of applications is possible and it is indispensable for professional surveillance.The PKI 2180 Professional Module Stethoscope Recorder creates an audio transparency that has not at all been possible before. The double piezoelectric transducer records conversations and noise through walls, windows, door frames and this in optimum audio quality. Up to 60 hours of conversation are recorded. In order to fully exploit the capacity,the PKI 2180 Professional Module Stethoscope Recorder is equipped with a remote control for ON/OFF, i.e. PKI 2180 can thus be switched to sleep mode. This way, monitoring operations lasting for months are possible. The PKI 2180 Professional Module Stethoscope Recorder is positioned at walls / windows or door frames as fast as lightning using the delivered „adhesive paste“. As a result of its small dimensions of only 70 x 24 x 27 mm camouflaged operation is possible. An integrated HF micro transmitter enables direct interception with the help of the delivered pocket receiver over a distance of 50 m. The HF micro transmitter can optionally be activated via the delivered remote control.
